Functionality is shown between
parentheses, (F) and (P), when the accession
number refers to rearranged genomic DNA or cDNA and the corresponding germline gene has not yet been isolated.

IMGT numbering and description of alleles for germline J-REGIONs start with the first nucleotide of the first codon. The accession number of a reference sequence is given for each allele.

Click on a gene name to get the alignment of the corresponding J-REGION alleles.
Click on an accession number to get the sequence and additional information (IMGT annotations, IMGT flat file, Coding regions...).
